A control system (11) controls the motion of a physical subject (36) such as a mechanical system via a single transducer (10) which alternates in a time- discrete manner between the task of reading a signal indicative of the state of the subject and the task of influencing said state by the application of a force. Control of motion or vibration is achieved through a series of actuating pulses interleaved with sensing operations. The same single transducer (10) alternately acts as input to the control system (11) from th e subject and output from the control system (11) to the subject. The control system (11) provides full and individual control of all important harmonic modes of vibration of a subject mechanical system.
